Output from guitar noticeably dropped in level , owner had a spare one to
complete the set. When I received it , setting both vol pots to minimum then
ohmage across output was 30 ohm. Now I'm inside, it is 3 to 5 ohms according
to switch setting. Pickup ohmages measure 7.82,3.80, 7.39K at the 3 switch
settings, which seems right, and consistent with wire tugs.
Now the bottom ohmage of the pots was not going to be 60 and 60 ohm or so to
give 30, one poor pot perhaps. I will remove the output screened lead
although nothing seems wrong with it, but the output socket was loose and
turning to an extentm requiting the screened lead to resist the turning.
Just leaves wear /plating problem at the tip contact of the switchcraft 1/4
in socket but it looks perfectly normal, contact point axial to jack until
deflected to the tip groove , etc. Pots measure consistent across tracks.
Switch seems ok but how to test other than by replacement
